It is the contention of Team Dinosaur that nearly all animals would be better in a smaller form.
 
This applies to: elephants, giraffes, tigers, hippos, wildebeests, cows, sheep, and most other land-based mammals.

This does NOT apply to: ducks (and many avians), which should be considerably larger.

A special category exists for gnats, who would be more dangerous in a larger form, but also easier to punch out of the air.
 
To take the elephant as an example, consider not the infant form of an elephant, but a mature and sprightly elephant the size of a football.

To accomplish animal rescaling Team Dinosaur has founded the Animal Miniaturisation Project. The avenues we’re currently most actively exploring in the Animal Miniaturisation Project are unnatural selection and genetic manipulation, viz. respectively: to select the smallest specimens within a group of animals and do away with the others, and to delete particular chromosomes involved in aging and development.

 The environmental argument here is that the small and cute versions of animals who would otherwise have to be kept at safe distance and with a great deal of living space, can become pets and thus proliferate to healthy numbers. The scientific/medical argument is that we might get a better understanding of genetic growth defects in humans. The decisive argument is that we in Team Dinosaur can’t think of a better world then one where tiny giraffes and elephants run free through our streets and open plan offices.
