Possible solutions to environmental crisis

Global warming - Causes

• Volcanic eruptions

• CFCs

• Man made chemicals

• Car exhaust fumes

• Green house gases

• Ozone depletion

Global warming - Effects

• Glacial retreats

• Melting of polar ice caps

• Sea levels rising and costal flooding

• Extinction of species

• Climate vhange

Global warming - Solutions

• Save energy

• Use CFC free aerosols

• Install filters in industry

• Raise prices of fossil fuels

• Reduce household waste

• Buy products with minimal packaging

• Recycle

• Plant trees

Endangered species - Causes

• Habitat destruction

• Water , air and ground pollution

• Illegal hunting

• Commercial exploitation

• Population growth

Endangered species - Effects

• Decline of species such as plants that are used in medicine

• Loss of biodiversity can result in loss of food, clean water and air

• Ecosystem destruction

Endangered species - Solutuion

• Restrict land development

• Create biodiversity action plans

• Protect species by legislation

• Discourage the exploitation of endangered species by trade and international band

Deforestation - Causes

• Trees cut / burned down

• Industrial development

• Tourism

• Acid rain

• Agriculture and food production

Deforestation - Effects

• Forest loss

• Displacement of indigenous people

• Climate change

• Severe water, air and ground pollution

Deforestation - Solution

• Conserve rainforests (they absorb greenhouse gases)

• Ecotourism

• Decrease need for products harvested from the rainforest

• Enforce recycling programmes

• Reduce demand for cardboard

Acid rain -Causes

• Car exhaust fumes

• Chemicals released in the air by industries

• Fires and volcanic eruptions

• Use of fossil fuels and fertilisers

Acid rain - Effects

• Adverse impact on people’s health and on natural ecosystems

• Acidification of lakes and streams

• Deterioration of materials and paints, including buildings, statues and sculptures

Acid rain - Solution

• Conserving energy or use of alternative energy sources

• Reduce fossil fuel use – drive less, slower speed, local shopping and holidays

• Governments could pass laws to help restrict pollution levels

• Limit processes known to generate high levels of acid rain
