Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels.
Currently, livestock make up 60% of the biomass of all mammals on earth, followed by humans (36%) and wild mammals (4%). [29] According to the 2019 global biodiversity assessment by IPBES, human civilization has pushed one million species of plants and animals to the brink of extinction, with many of these projected to vanish over the next few ...
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
[10] NASA plays a critical role in providing the scientific data necessary for understanding and addressing climate change globally. Through missions like GRACE, ICESat, and Sentinel-6, NASA documents crucial changes in the Earth's ice sheets and sea levels, offering invaluable insights for both mitigation and adaptation efforts. Although not ...
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]
Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services. Habitat destruction has altered nitrogen, phosphorus, sulfur, and carbon cycles , which has increased the frequency and severity of acid rain , algal blooms , and fish kills in rivers and oceans and contributed tremendously ...
Tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity. [21] Other parameters that affect tropical rainforests are carbon dioxide concentrations, solar radiation, and nitrogen availability.
I = (PAT) is the mathematical notation of a formula put forward to describe the impact of human activity on the environment. I = P × A × T. The expression equates human impact on the environment to a function of three factors: population (P), affluence (A) and technology (T). [1]
