What are the biggest threats to biodiversity? Why?

No, please listen. I do not talk about the reason why South America's rainforest will become savanna in 50 years. I am not talking about polar bears in Surabaya. For biodiversity there is nothing more important than the fact that the ocean temperature is rising. This will lead to the next mass extinction. That happened before - if you want to learn more about the Google Permian Triassic boundary

Well, what happens when the ocean warms up several times? First, the coral fades. Shelf life will disappear where the fish dies (eg on the Great Barrier Reef). This is a big problem for our marine biodiversity. But it is by no means a threat. wrong

Phytoplankton Small microorganisms that photosynthesize. The bottom of the food chain. Almost the whole ocean. When they die, the marine life die

What are they doing now right now? That's right. It dies like a fly. It is a group. So far 1% per year. I do not hear much. But when walking along the food chain, remember that only 10% of the energy is transmitted to the next level of the food chain. Therefore, when eating plants eats plankton, you can use 10% of the energy produced by phytoplankton. Therefore, in order to build biomass of fish, biomass of phytoplankton fish needs to be multiplied by 10. If this fish can be eaten by looted fish, it needs 10 times more biomass than a peaceful fish. It is 100 times the biomass of plankton. You already guessed - phytoplankton is very small, we need a lot of it to maintain this food chain. When it kills 1%, it kills many animals. With so many food chain levels. If plankton's biomass production is low, the number of peaceful fish will decrease and the number of predators will decrease. Let's see the framework of 10 years which is half of my life. 90% of plankton causes 90% of peace fish. Fucking every year. In the second year, it was 81% of plankton and fish we started. About 20% of marine life dependent on plankton died in the past 20 years. We can not see it, we live on land. If you do fish it may be like a shelf, but it is rare that it is public at sea.

Why does phytoplankton die? This is an interesting thing. The sea level is too hot, so it will sink deeply. The sun is a little less. It can not do much photosynthesis. It produces 1% less biomass. However. This is the reason that the sea disappears little by little every year.

Oh, by the way, phytoplankton now produces about half of the oxygen on the earth. It is worth considering

Reducing our ocean biodiversity is the greatest threat to human survival. As the number of marine organisms decreases, the quality of life of human beings declines. What is the reason for this imminent mass extinction and the impending threat to our group survival? Everything starts with inspiration. Therefore, each Parley is a dedicated theme collection presented to a viewer carefully selected by Parley Speakers. Talks are designed to outline the general state of the ocean, provide specific reasons, and receive assistance from related initiatives or projects.

Reference example (15 points) to explain the threat to biodiversity hotspots and why it is important Biodiversity Hotspots are areas of the natural environment including the world's most concentrated animals and plants. Please enter. However, many of these ecosystems are threatened by factors critical to the health of the environment, such as climate change, urbanization / land use, and tourism development.

Especially in Africa, there is still a big research gap in understanding the mechanism and impact of urbanization on wildlife. The unprecedented speed of the current urbanization is a major threat to biodiversity. That is one of the biggest environmental problems of our time. Accurate understanding of how urbanization affects wildlife is important to help animals survive nearby. Urbanization leads to segmentation of habitats. There, larger contiguous habitats are divided into smaller unbound plaques. It also causes loss of habitat by increasing the number of roads and buildings that do not produce biomass. This exposes wildlife to new artificial stress. Physiological and ecological constraints directly affect organisms, but also alter host-parasite and predator-prey interactions
