Measures to stop pollution

International Efforts

Pollution Pollution tends to travel between

countries by wind or water, e.g. haze in Indonesia

Countries have agreements to work together to stop pollution

Earth Summit Organized by United Nations to discuss

sustainable development Took place in 1992, 2002 and 2012 Commitments made in 2002 include:

Manage toxic chemicals Increase access to clean water Build proper sewage systems

SEA Region Singapore Indonesia Malaysia

Mandatory Ship Reporting System Info. on damage and defects Report any pollutants released Authorities trained to respond quickly

National Efforts: Singapore’s Efforts to Protect the Environment

Enforcing Laws and Regulations Enforce laws to control amount of

pollutants emitted by industries Ensure that companies treat their waste

before disposing them National Environment Agency (NEA)

Using Alternative Sources of Energy Use “clean” energy Wind energy, hydroelectricity and solar

energy

Use Advanced Technology Use advanced technology to treat waste

and remove pollutants Reduce impacts of pollution on the

environment Build sewage treatment plants to treat

waste before it is released into water bodies

Landfill Huge pits in the ground for disposal of

solid waste Waste dumped and covered with soil Take up plenty of space One time use

Pulau Semakau Landfill

Incineration Burn waste at high temperature Reduces volume of waste by 90% Energy produced converted to electricity Releases dust particle to air (pollution) Some waste can’t be burned (concrete)

Educate Public Encourage people/industry produce less

waste Campaign and talks informed-harmful

Individual Methods to Reduce Pollution

Pollution • Affects over 100m people

• 2m people die prematurely each year from bad air

• Hole in the ozone is 8.2 million sq miles large

Solutions - Awareness• Ensures that people are motivated to solve

pollution

• Possible methods usedo Educationo Statistics

1. Use of private transport

2. Incorrect waste disposal

3. "Reduce"

4. Use of aerosols

Solutions - Minimizing

Minimizing use of private transport• Exhaust created leading to dust particles in the

air

• Public transport etc. means that less exhaust is created

Minimizing incorrect waste disposal• Throw rubbish in the right place

• Litter often ends up swept into water bodies

"Reduce" • Try to minimize unneccessary use of materials as

much as possible

• e.g, Print on both sides of the paper instead of printing on 2 sheets

Minimizing Use of Aerosols• The use of aerosols give of CFCs.

• CFCs are an Ozone-Depleting Substance

• (Daniel please give us a complex chemical explanation)

Solutions - Maximise1. Carpooling/public transport2. Recycling3. Reusing

Carpooling• When possible, catch a ride from your neighbour.

(Thank you Shaun)

• This reduces the number of cars on the road, also reducing pollution from car exhaust.

Recycling• Makes unusable materials usable again

• Reduces waste

Reusing• Use items more than once

o e.g. bringing own bags to shopping

• Reduces waste aso Less things thrown away o Less things have to be made due to less demand

Solutions - changing lifestyles1. Going green

2. Getting involved

Going green• Switching lights off when not in use

• Energy saving light bulbs

• Buying green products

• Reduces the amount of waste produced

Getting involved• Make an effort to learn more about

o Environmento Environmental problems present

• Involve ourselves in environmental conservation plans
