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 ...
Since the 1960s, nearly 50% of tropical forests have been destroyed, but this process is not limited to tropical forest areas. Europe's forests are also destroyed by livestock, insects, diseases, invasive species, and other human activities. Many of the world's terrestrial biodiversity can be found living in the different types of forests.
Many animal feeds have a high fish meal or fish hydrolysate content. In this way, marine toxins are transferred back to farmed land animals, and then to humans. Phytoplankton concentrations have increased over the last century in coastal waters, and more recently have declined in the open ocean. Increases in nutrient runoff from land may ...

A diagram of the typical drivers of ecosystem collapse. [1]While collapse events can occur naturally with disturbances to an ecosystem—through fires, landslides, flooding, severe weather events, disease, or species invasion—there has been a noticeable increase in human-caused disturbances over the past fifty years.
Degraded forest in Lahnberge, Germany: the soil is being washed out due to lack of vegetal cover, some trees are losing ground and they appear to be sick (photo by Andreas Trepte). Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does ...
The fund is used in various areas, including the management of public forests and protected areas, control, monitoring and environmental enforcement, sustainable forest management, economic activities developed from the sustainable use of the forest, ecological and economic zoning, land planning and regularization, conservation and sustainable ...
Today, developed countries continue to utilize timber for building houses, and wood pulp for paper. In developing countries almost three billion people rely on wood for heating and cooking. [ 35 ] Short-term economic gains made by conversion of forest to agriculture, or overexploitation of wood products, typically leads to loss of long-term ...
