What are the effects of climate change Wikipedia?
Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification. Other possible effects include large-scale changes in ocean circulation.
How is climate change affecting animals birds and plants?
“Climate change affects ecosystems, habitats and species with increasing velocity and continuity.” Altered temperature, precipitation and moisture, a generally more variable climate, and more extreme weather are hallmarks of climate change that directly affect birds.
What are the effects of global warming on food production?
Global warming could lead to an increase in pest insect populations, harming yields of staple crops like wheat, soybeans, and corn. While warmer temperatures create longer growing seasons, and faster growth rates for plants, it also increases the metabolic rate and number of breeding cycles of insect populations.
What wildlife means?
Wildlife traditionally refers to undomesticated animal species, but has come to include all organisms that grow or live wild in an area without being introduced by humans. Wildlife can be found in all ecosystems. This includes such animals as domesticated cats, dogs, mice, and rats.
How can we manage wildlife?
There are two general types of wildlife management:
- Manipulative management acts on a population, either changing its numbers by direct means or influencing numbers by the indirect means of altering food supply, habitat, density of predators, or prevalence of disease.
- Custodial management is preventive or protective.
