There are some very big issue affecting the world and climate that should be tackled first rather than trying to get individual habits to change, which will have a much less significant effect.
Such as the fires in Indonesia

in 2015 “The fires released enough greenhouse gasses for Indonesia to produce more daily emissions than the United States for 38 days.”

“Forest and land fires burning in Indonesia have released 360 million tonnes of carbon dioxide since August, said Singapore’s Minister for the Environment and Water Resources Masagos Zulkifli on Thursday (Sep 26).
That’s more than Spain’s emissions for the whole year in 2018, he added.

“Greenpeace estimates that in the past 50 years, more than 74 million hectares of Indonesia’s biodiverse rainforests – an area twice the size of Germany – have been chopped down, degraded or burned.
They have often been destroyed to make way for plantations for the lucrative palm oil and pulpwood industries, particularly on Sumatra and Borneo islands, with fires often started illegally to clear land.”
and then there is the Amazon :
“The fires in Indonesia are far smaller than those in the Amazon, the world’s biggest rainforest.
Close to 2.5 million hectares of land was burnt in August, Greenpeace has said, citing data from INPE, Brazil’s national space research institute.
Wildfires in Bolivia have torched 2 million hectares of forest and grassland since August, while in Brazil, 88,816 fires were recorded from January to the end of August, over half of them in the rainforest.”
More developed countries need to take action – maybe pay higher taxes to pay these countries for the loss of not using one of their natural resources.
Plastic pollution needs an engineering solution to go clear the oceans – we can collect shed loads of fish from it, why not plastic?
