Here is how the climate will affect the wetlands in North America

,
Wetlands, a study from the US explains, will experience substantial drying during the summer. Impacting habitat and biodiversity from Florida to Mississippi to southeastern Canada
Biosolids are a by-product of the wastewater treatment process and can be used as fertilisers as they are rich in nitrogen and phosphorus. Photo: City of Geneva ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 DeedCity of Geneva ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 Deed

US bio-fertilisers are useful but watch out for contamination

,
Used as fertilisers, biosolids produced by wastewater treatment can be very beneficial for the soil. This is also why, according to a study, it is important to analyse their content to prevent contamination phenomena
Driven by climate and agricultural activities, the greatest soil loss in the United States has occurred mainly in the Central Great Plains, on slopes and in cultivated soils.
