The desert locust disaster that has been raging in East Africa and South Asia for several months which has caused serious damage to agricultural production in many countries and many countries have declared a state of emergency. China’s locust disaster prevention and control team, after investigating the disaster in Pakistan, said that locusts are now entering the stage of mating and breeding, and this locust disaster is more serious than expected.
According to the FAO, global warming is the main cause of this locust disaster, which also raises the global concerns about climate change.
In 2019, East Africa began with drought and ended with flood. In mid-2019, droughts across Africa continued to increase and rainfall decreased.Under the condition of high temperature, drought and soil water content as low as 10% – 20%, locusts can lay 200000-400000 eggs per square meter
At the same time, plant water content is lower, locusts grow faster, dry land vegetation itself is very rare, locusts eat up quickly, migration frequency is also greatly accelerated.
The FAO of the United Nations has warned that the situation in East Africa is very critical at present. The number of desert locusts has reached 360 billion
The locust disaster in Kenya is the most serious in 70 years in the country. The length and width of a single locust group reach 60 km and 40 km respectively.
According to local authorities in Kenya, generally, a locusts group of one square kilometer can contain 40 million to 80 million locusts, and each locusts can eat the food equivalent to its ow weight, and can eat 35000 people’s rations in a day, so there is no particle where the locusts group passes.
Desert locusts have leaped over the Red Sea and the Arabian Sea. They have ravaged more than 20 countries, including Pakistan and India, and have accumulated more and more insect resources in flight. Somalia and Pakistan and other countries have declared a state of emergency.
On January 31, Pakistan declared a state of emergency, the most serious locust disaster since 1993. Locusts have also been found in areas where no locusts have beenfound before. Relevant data show that Pakistan’s wheat alone may lose as much as $1 billion.
In February, locusts began to invade Rajasthan and Gujarat, India. As many as 5.55 million mu of farmland was attacked by locusts, causing economic losses of over 10 billion rupees.
The food and Agriculture Organization of the United Nations predicts that the climate conditions on both sides of the Red Sea and the horn of Africa from February to mid March will still be conducive to locust reproduction. These desert locusts reproduce once a month in a climate of 40 degrees Celsius, and each generation means that the number of locusts will increase 20 times. Without containment, the number of desert locusts could even increase to 500 times in June.
African locust disaster, Australian mountain fire and Brazilian Amazon rainforest have set off intensive and sustained fires. In 2019, global warming has caused frequent extreme weather events. The climate data since February has again raised concerns about global climate.
According to foreign media slashgear, January 2020 is the hottest January on record, highlighting the overall trend of global climate change. In fact, accordingto NOAA’s 141 year record, the global land and sea surface temperature in January 2020 is 2.05 degrees Fahrenheit higher than the average temperature in the same month of the 20th century.
At the same time, the Antarctic temperature has also reached a new high, which makes scientists more worried.
According to the guardian, Antarctica has seen several temperature peaks since February. On February 9, Antarctica broke through 20 ℃ for the first time since its own record. Scientists call the number “unbelievable and very unusual.” Antarctica has become one of the fastest temperature rising regions on the earth.
In addition, 14 scientists from 11 institutions at home and abroad jointly released the latest ocean observation data, which shows that after the record warming of the oceans in 2017 and 2018, the ocean warming in 2019 has reached a new high – the warmest year for the oceans since the modern ocean observation record.
In Guterres’ speech in Pakistan, he urged greater action to achieve the 2030 agenda for sustainable development. The way to deal with the climate crisis is global solidarity, backed by global action. He said that today’s challenges to sustainable development and human progress are regardless of national boundaries. It also calls on governments, enterprises civil society and individuals to work together to create “unstoppable momentum” for the achievement of sustainable development goals. He said “Climate change is the biggest threat to our planet. I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change on this planet we all share. This global initiative will fund scientists, activists, NGOs – any effort that offers a real possibility to help preserve and protect the natural world. We can save Earth. It’s going to take collective action from big companies, small companies, nation states, global organizations, and individuals. I’m committing $10 billion to start and will begin issuing grants this summer. Earth is the one thing we all have in common – Let’s protect it, together.”
Jeff, the world’s richest man, has been promoting many of Amazon’s climate initiatives over the years, and the company has funded a network of wind and solar power plants as part of its long-term goal of 100% using renewable energy to power global infrastructure. Amazon has also promised that 80% of its global infrastructure power supply will come from renewable energy by 2024 and 100% by 2030, compared with 40% currently.
Coincidentally, the British government said it planned to invest 1.2 billion pounds to develop the world’s strongest climate prediction supercomputer. The new supercomputer, which will be run by the Met Office, will be used to help predict global climate change more accurately.
South Africa’s president, Ramaphosa, said the coal dependent country would soon turn to renewable energy as a way to alleviate power shortages. “We have made this decisive change in the path of energy development at a time when mankind is facing the greatest threat to survival – climate change” he said He also vowed to finalize the climate change bill and its framework to reduce the country’s vulnerability to global warming.
Hungarian prime minister Orban announced the “Climate Action Plan” on the 16th. By the end of 2030, the plan will reach 90% of electricity and carbon most of which will come from nuclear energy and solar energy.
Why so many experts choose solar energy products as the direction of environmental protection? Let’s know more about the advantages about solar energy.
It is estimated that in the past 1.1 billion years, the sun has consumed only 2% of its own energy. In the next billion years, the sun will not change significantly.
Therefore, the sun can be used as a permanent energy for human beings and it is inexhaustible. If it gives the ground 15 minutes of energy, it is enough for
the world to use for a year.
It is generally believed that there are abundant solar energy available in areas within 50-60 degrees latitude from north to south. As long as a sum of money
is invested initially, such as installing a batch of solar street lamps or solar energy systems, it will not cost money in the future, just need a little maintenance.
Coal, oil and other fossil fuels will produce harmful gases and waste residues, but the use of solar energy will not bring pollution, and will not discharge any
substances that have adverse effects on the environment, so it is a clean energy.
Solar energy does not increase the heat load on the earth, which is a particularly important feature of solar energy. If coal and oil are used, the heat load of the
earth will be increased, and the temperature of the earth will be increased.
Nuclear power generation will have the risk of nuclear leakage, once the leakage will cause a great ecological crisis, and solar energy absolutely does not have
this situation, is very reliable.
Our company’s original intention is to contribute to environmental protection and create intelligent new energy – solar street lamp. In the selection of energy solar street lights do not have pollution and it is inexhaustible solar energy.
Each of us in this world should not have the idea of “being alone”.
Emergencies in other places are not a matter of a country or a region. On the contrary, it may mean that the whole human society is facing a structural crisis and we need to face it together. As an ordinary person, we can choose high-quality solar street lights and solar energy products from the beginning to do our best for environmental protection.
