Environmental Sustainability Background information- what's going on?

Environmental sustainability involves managing resources to ensure they are available for future generations, focusing on renewable and non-renewable resources. Biodiversity plays a key role, encompassing ecosystem, species, and genetic diversity, each contributing to the resilience and adaptability of life forms.

biodiversity

Monoculture
4 components of habitat
3 types of biodiversity
Ecosystem biodiversity

Ecosystem diversity

Genetic biodiversity

Genetic diversity is having genetic variation within species such as-


Species biodiversity

Species biodiversity is having many different types of species

Why is biodiversity important?
Living planet report

energy and electricity

electricity
clear air alliance

Use energy more efficiently and waste it. Also better technology to decrease efficiency loss

Stop using fossil fuel energy production

Use energy more efficiently and waste it. Also better technology to decrease efficiency loss

non-renewable

gas fired generation

renewable sources

Tidal energy

A turbine placed near a shore through which tides move in and out.

Expensive to set up

You have to be near a shore

Might need frequent replacement due to rusting

these are some of our disadvantages

hydro electricity

Building dams can disrupts the flow of water which has a lot of side effects. such as: Salomons can't go back up a river, the habitat around the dam can be destroyed.

Dams

biomass

If wood is the source that is burning then it can lead to deforestation

windmills

Environmental Impacts/disadvantages:

There isn't always wind

Takes up a lot of land

Birds and bats can run into them causing them to die

The noise can disrupt birds and animals


Solar

Environmental Impacts


Problems with lithium and cobalt

THE ENVIRONMENTAL IMPACT OF LITHIUM

the risks in polluting local water sources arise here, with examples of Salar de uyuni and Salar de Atacama. This process involves lo

hydrogen fusion

fusing hydrogen and oxygen together releases electrical energy.

waste

Plastic waste
coke knew their plastic would trash the planet.

at first the coke bottles we're returnable in the studies, take it back was the best option for the environment in 1969. as well as throw it out was more profitable,but they had lied.

Landfill
Incinerator in Ottawa

Councillors were updated on long-term plans to deal with Ottawa's solid waste, as the Trail Road landfill approaches capacity. In 2023 Ottawa residents paid on average to get $185 each year for waste services. but even if councillors opt against the technologies, staff say the rates will likely double within the decade.

city staff have provided an estimate to how much cost for a garbage collection per household?! and in about the next 30 years based on 3 scenarios "anaerobic digestion (orange), waste-to-energy incineration and anaerobic digestion (blue) or mixed waste procession and anaerobic digestion (green).


Staff have come up with dozens of recommendations they said will ensure the site is viable for 14 years, including:

This plan incorporates very few recent moves from the council including heavily debated decisions, like to limit curbside trashes.

water waste
electricty waste

statictics about electricity waste, About 65% of energy in power plants we're lost in 2013 that is about 22 quadrillion. When energy is burned to relate heat, this boils water into steam. the steam is sent through turbines and this creates electrical energy although only two thirds of this energy actually makes it onto a grid to create electricity due to the way electricity is produced.

phantom power
food waste

Food waste in canada is about $31 billion worth of food ends up in landfills and composters each year sadly.

most households in canada on average wastes about

$28 worth of food each week as well. approximatly 47% of food is wasted in canada. This mainly aims at households, and in general 53% of wasted food is generated.
