Ecotones are particularly significant for mobile animals, as they can exploit more than one set of habitats within a short distance. The ecotone contains not only species common to the communities on both sides; it may also include a number of highly adaptable species that tend to colonize such transitional areas. [ 3 ]
Science, technology, society and environment (STSE) education, originates from the science technology and society (STS) movement in science education. This is an outlook on science education that emphasizes the teaching of scientific and technological developments in their cultural, economic, social and political contexts.
An important ecosystem function associated with biodiversity is pest control. [23] Control species can suppress pest populations and reduce loss of crop yields without the negative impacts of chemical pesticides. [24] This has economic benefits and maintaining natural pest control is important to humanity's ability to grow crops. [25]
The South Amazon Ecotones Ecological Corridor (Portuguese: Corredor Ecológico dos Ecótonos Sul-Amazônicos) is a proposed ecological corridor connecting conservation units and indigenous territories that form an ecotone, or transition between the south of the Amazon rainforest and the north of the cerrado of Brazil.
Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion.The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas, genetically modified foods and global warming.
Natural habitats can provide Ecosystem services to humans, which are "any positive benefit that wildlife or ecosystems provide to people." [10] The natural environment is a source for a wide range of resources that can be exploited for economic profit, for example timber is harvested from forests and clean water is obtained from natural streams.
Changes in precipitation appear to be the most important driver. [ 55 ] [ 56 ] It's been estimated that by 2050, climate change alone could reduce species richness of trees in the Amazon Rainforest by 31–37%, while deforestation alone could be responsible for 19–36%, and the combined effect might reach 58%.
The economic value of natural capital and ecosystem services is accepted by mainstream environmental economics, but is emphasized as especially important in ecological economics. Ecological economists may begin by estimating how to maintain a stable environment before assessing the cost in dollar terms.
