Overexploiting sea otters resulted in cascade effects which destroyed kelp forest ecosystems. Overexploitation of species can result in knock-on or cascade effects. This can particularly apply if, through overexploitation, a habitat loses its apex predator. Because of the loss of the top predator, a dramatic increase in their prey species can ...
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
Plant 3 billion trees by 2030. Restore at least 25,000 kilometers of rivers, so they will become free flowing. Reduce the use of Pesticides by 50% by 2030. Increase Organic farming. In linked EU program From Farm to Fork it is said, that the target is making 25% of EU agriculture organic, by 2030. [245] Increase biodiversity in agriculture.
[10] [11] The relationship between deforestation and climate change is one of a positive (amplifying) climate feedback. [12] The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth.
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.

Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, [11] [12] [13] neoliberal economic policies [14] [15] [16] and rapid economic growth, [17] overconsumption, overexploitation, pollution, and deforestation.
Afforestation critics argue that ecosystems without trees are not necessarily degraded, and many of them can store carbon as they are; for example, savannas and tundra store carbon underground. [10] [11] Carbon sequestration estimates in these areas often do not include the total amount of carbon reductions in soils and slowing tree growth over ...
