Fast fashion, the practice of large companies producing trendy, low cost items, has become more controversial with the more clothing waste that it produces. Many major fast fashion brands, such as H&M and Gap, produce items at high rates to keep costs low, but at the expense of quality and major environmental impact. These brands do however provide nicer clothing to those who may not be able to afford sustainable and designer brands.

Millions of tons of electronics are discarded each year and end up in developing nations, where they hurt the environment. Is it morally permissible for nations to sell potentially hazardous e-waste to willing buyers in developing nations? Do manufacturers have a moral obligation to create products with longer lifespans, even if they would earn less money as a result? How should manufacturers, governments, and consumers solve this problem?

The countries that emit the most carbon dioxide catalyze climate change while countries that emit the least amount bear its consequences most. Peter Singer proposed that each nation has a right to produce CO2 up to a certain amount and countries that pollute below the limit can sell their emission rights to countries that produce more.
