The warming of ocean waters has caused coral bleaching and the degradation of coral reefs, which are vital to marine biodiversity and fisheries. Coral reefs support a large proportion of the world's fish species, providing food and livelihoods for millions of people. As ocean temperatures rise, the symbiotic relationship between corals and ...
Other effect of deforestation in the Amazon rainforest is seen through the greater amount of carbon dioxide emission. The Amazon rainforest absorbs one-fourth of the carbon dioxide emissions on Earth, however, the amount of CO 2 absorbed today decreases by 30% than it was in the 1990s due to deforestation. [35]
One of the world's largest and most dense rainforests is the Amazon rainforest in South America. Rainforests are disappearing across the world, and at an alarming rate in Brazil. Since the 1980s, more than 153,000 square miles of Amazonian rainforest has fallen victim to deforestation. [6]
It has been projected in 2015 that many fish species will migrate towards the North and South poles as a result of climate change. Under the highest emission scenario RCP8.5, 2 new species would enter (invade) per 0.5° of latitude in the Arctic Ocean and 1.5 in the Southern Ocean. It woul also result in an average of 6.5 local extinctions per ...
The paper's worst-case scenario for both stressors had only 53% of the original rainforest area surviving as a continuous ecosystem by 2050, with the rest reduced to a severely fragmented block. [57] Another study estimated that the rainforest would lose 69% of its plant species under the warming of 4.5 °C (8.1 °F). [58] [failed verification]
Deja el Plastico (Ditch the Plastic) is aimed at reducing plastic pollution in California; its efforts helped lead to the passage of the state’s ban on single-use plastic bags in 2016.
Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [2] Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. [3]
How bad is the world’s plastic problem? Few disagree that the level of pollution has reached alarming heights. Between 2000 and 2019, annual production of plastics doubled to 460 million tons.
