“A well-run curbside recycling program can cost anywhere from $50 to more than $150 per ton… trash collection and disposal programs, on the other hand, cost anywhere from $70 to more than $200 per ton. This demonstrates that, while there’s still room for improvements, recycling can be cost-effective.” Is recycling cost efficient? The cost effectiveness …

In general, you will need an environmental permit from the council if the boiler is using biomass fuel from natural sources, e.g. wood pellets, and has a rated thermal input >20 MW, or if the boiler is burning waste or waste-derived biomass, and has an aggregate capacity of 50kg or more per hour. What is …
The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats. How does matter flow between trophic levels and among ecosystems? Next, energy and matter …
Bottle caps are recyclable, but they often get lost during the recycling process because of their small size. Put your bottle caps in a steel food can, and when it’s nearly full, crimp it closed and recycle the can and its contents together. Can you recycle a beer bottle cap? You now know that beer …
In the BIDE models, habitat fragmentation affects the extinction threshold by increasing the amount of edge in the landscape, which increases the probability of individuals leaving habitat cells and moving into matrix cells, where the mortality rate is assumed to be higher. How does habitat fragmentation cause extinction? Researchers have long assumed that when animals …

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies. What is essential for ecosystem health? A healthy ecosystem is essential …
What are engineers doing about climate change? Another way engineers can help reduce CO2 emissions is to sequester it — capture and store the CO2 from power plants right when it’s emitted, so that it can’t get into the atmosphere. Studies are also looking at ways to make trees and other vegetation more efficient as …
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3). What other changes in an ecosystem can affect populations? Important direct drivers include habitat change, climate change, …
