Negative consequences: one of the most studied phenomena is its effect on egg shell thickness, this has been researched on seagulls and other bird species. DDT inhibits proper calcium metabolism, avoiding proper function of egg shells, they became fragile and tended to produce a high rate of miscarriage, leading to a sharp decrease of population size.

Terrestrial vegetation adapted a water being scarce so desiccation risk-free practices is mandatory; vegetation adapted an epidermal cuticle with regulated stomatal pores. Air is way less dense than water so vegetation adapted with structural help extra to lignify cellular partitions contained in the vascular gadget. Low thermocapacity of air so vegetation adapted so huge temperature stages could be tolerated severe O2 content - antioxidation is needed as risk-free practices Marine vascular plant evolution is unusual because of the fact they desire a million – Adapt tolerance to submergence with much less CO2 obtainable and much less O2 yet they maintain at an epidermic and cuticle that restricts water uptake besides as loss. vegetation are cardio so nonetheless desire O2 for cellular respiration for roots deep in sediment. 2 – Tolerance to salinity 3 – Adapt to hydrophilous pollination 4 – Adapt anchoring gadget for turbulent ecosystem - vegetative anchorage and unfold by potential of rhizomes- burial tolerance as against exposure tolerance
