Too many animals and plants disappear due to climate change

Climate change (climate change) shifts climate zones. Species will respond to new climate conditions. The change of species will change the composition and geographical distribution of ecosystems. Synonymous with this will be the disappearance of some animals or plants or significantly reduced.

According to Prof. Dr. Nguyen Duc Ngu, Vietnam Association for Nature and Environment Protection, the documents have recorded a change in the climate boundary that has been recorded in some parts of the world. The major plains in the United States are an example of a typical area of ​​climate change that occurred during the last 30 years of the twentieth century. It is also noticed that some birds in Europe spring migrate later.

Studies have also shown that some species will better adapt to climate change while others will not adapt to degradation gradually. In general, species are inherently sensitive to climate change conditions, or are already at high risk, climate change will be a major threat to them. A review showed that if the temperature rises to 10 ^° C, tropical forests in Queensland, a world natural heritage in Australia can be reduced by up to 50%, while some lost trees can reach 40%.

Scientists say there are about 300,000 species of plants, 60,000 mollusks (molluscs), 30,000 species of crustaceans, over 1,000,000 species of insects, 22,000 fish species, and so on. 4,300 species of amphibians (amphibians), 6,000 reptiles, 9,000 species of birds, 4,600 species of mammals. The number of virus species, cyanobacteria, yeast, filamentous fungi, high-grade fungi also appeared a lot. Climate change with more extreme climatic conditions such as droughts, forest fires, floods . will make species more likely to be reduced. High mountainous areas will also be strongly affected. Many mammals and birds will be reduced due to inappropriate living conditions, reduced nutrient resources.

Climate change causes high temperatures, combined with abundant light, to promote photosynthesis, leading to increased assimilation of trees. In particular, increased CO ₂ content will contribute to the development of forest ecosystems. However, due to the increased evaporation rate, soil moisture will decrease, resulting in a decrease in the biomass growth index of forest trees.

The risk of genocide of animals and plants increases, a number of important plant species such as: agarwood, huang huong, po-mu, red knock, mahogany… can be exhausted. Increased temperature and drought increase the risk of forest fires, develop pests and diseases that destroy forest trees.
