a) We have to dress up like for summer/ winter. Because we have shining mornings and dark cold nights. So we go out in the mornings with sweatshirts, t-shirts, ligth sweaters...and have to carry heavy jackets to use later on. It's a bit messy when you have to carruy also your backpack and maybe other stuff.
b) At nights, we cover up with an extra blanket, and have thicker pijamas. For you it might not be strange, but for us, that have not been accostumed to this practices because we had "warmer winters" it's very difficult. And the risk of catching a disease gets bigger because we are exposed to AH1N1 flu. Our school was in quarantine for one week, later on, the Ministry of Education in Peru cancelled all classe in the country for 3 weeks, to stop expansion of the virus.The thing is, the colder the climate gets, the more vulnerable we are to the flu (because it starts like a normal-every-day-ordinary flu!).
c) As mentioned before, pets are vulnerable to climate change. In summer, their hair keeps them like in a live sauna (and they are with their tongues out all the time), and street dogs in winter can't usually find shelter to hide from the cold nights.
d) Thinking of a positive thing, some actions are being taken into policies (private or public). There are more environmental and climate protective projects. International cooperation helps our government to improve living conditions of biodiversity and human life.
