Study Notes

End of life of a product is the last stage in its life cycle, involving disposal, recycling, reusing, reconditioning, or reducing waste.
Designing for a product's end of life should be integrated into the product development process from the start.
Environmental impacts from organizations' activities include global warming, air and water pollution, poverty, resource depletion, biodiversity loss, ozone depletion, and land degradation.
Global climate change is a critical issue, with CO2 emissions contributing significantly and various sectors like power, agriculture, and transport being major emitters.
Air pollution causes millions of deaths annually, while over 1 in 6 people globally lack clean water access, leading to significant mortality.
Poverty is escalating, especially in less developed countries, impacting food sustainability and causing hunger and malnutrition for 1 in 6 individuals worldwide.
Resource depletion is a growing concern as natural resources like water are being unevenly consumed across different regions, with waste management also posing challenges.
Biodiversity loss threatens numerous species, with predictions indicating potential extinction of 13% of plants, 25% of mammals, and one-eight of bird species if current trends persist.
